I just got my new STi-Driver today. When I opened the Owner's Manual there was an insert that said Revision to your Owner's Manual. On the card it states that the STi has a new software installed called TSR Signal Ranking Software. A couple post down from mine I was reading best settings for the STi. Unless I missed it, I did not see anyone metion turning TSR on or off. By default it is off. If anyone knows the Pros or Cons of TSR, could you please share them. Thanks in advance. The build on my STi is 3509.
